Their bond grows stronger within no time. Azhagan is also well liked by Radha`s mother. However, his proximity to Radha and her mother doesn`t sit well with Radha's father Vinod. Things take an ugly turn when Vinod's construction company decides to acquire the land that belongs to Azhagan`s community.
